摘要：

Transversal filter and circuit models are used for a SAW delay-line transfer-function derivation. The design procedure of SAW sensor delay lines is described. Calculation and measurement results of a SAW delay line for a centre frequency of about 70 MHz on a 128 degrees IX LiNbO3 substrate are presented. Very goad agreement is obtained between theoretical and experimental parameters of the delay line. (C) 1998 Elsevier Science S.A. All rights reserved.
